Abstract

The invention concerns an air-operated device used to screw nuts and screws.According to the invention, the device includes an air-operated cylinder in which a piston with a rod oscillates under the compressed air, as well as an elastic system consisting of some springs placed on both sides of the piston, which stimulates into a reciprocal motion a slideblock provided with ratchet pushed by a spring that activates a ratchet wheel provided with a hole for screws or nuts.
